So I noticed something that amused me while watching Big Bang Theory the other night — apparently Sheldon has a holographic display on his laptop. The real-world explanation, of course, is the conceit of television’s visual language, but that’s not nearly as much fun to believe.

So I noticed something that amused me while watching Big Bang Theory the other night — apparently Sheldon has a holographic display on his laptop.

Obviously, some evidence in the form of screenshots is in order (all from Season 4, Episode 15, “The Benefactor Factor”, though I noticed this in Episode 14, “The Thespian Catalyst”, as well).

First up, a shot of Sheldon videoconferencing with Amy. This is mostly to set the scene, there’s nothing much to see here.

Sheldon videoconferencing with Amy.

Next, a POV shot of what Sheldon sees while sitting directly in front of the computer.

Compare those last two shots. In the first shot, from Sheldon’s POV, we see Amy from directly ahead. She’s looking directly into the camera, as would be expected. However, in the second shot, she’s turned slightly to her right, giving us a slight profile shot (and while it doesn’t really translate in still shots, this isn’t because she was shaking her head or momentarily turned her head for some reason — she holds her head in this position through the entire shot).

The final impression is that as the camera switched from Sheldon’s POV to the over-the-shoulder shot, the perspective changed in our view of Amy, so that we see her from the same angle as if the two characters were speaking face-to-face rather than over video chat…but the only way that could happen would be if Sheldon’s computer had a holographic display!

With our normal, flat, non-holographic computer screens, of course, even when moving to the side of a computer screen, we would still see the other party looking straight into the camera…so we’d see the image something like this:

What real-world laptops would display

Of course, in the visual language of television, that looks odd. We expect characters to look at each other, and we know that Sheldon and Amy are looking at each other, so the technically correct shot seems a little odd, as Amy is still looking directly out of the screen, apparently at the viewer instead of at Sheldon. The solution, then, is to have her turned slightly to her right when filming those sequences so it still appears that she’s looking directly at Sheldon, even though it gives the somewhat amusing impression that Sheldon has a laptop far more advanced than any currently on the market (as does Amy, as she’d have to have a laptop that can both film and broadcast 3D video chat streams) — but then, would we really expect anything less from Sheldon Cooper? ;)

I have no idea how often this technique is used on other shows, as this is one of the few times I’ve noticed it. In fact, the only other time I can think of that I noticed this technique being used was in Star Trek (TNG comes to mind, though I can be relatively sure that it was also done this way in DS9, VOY, and ENT). However, in the Star Trek universe, it’s known (at least to the more geeky technobabble obsessed fans) that the main display screen on the bridge of the Enterprise is a holographic display, and it’s not that far-fetched to believe that the smaller displays might be as well, so the conceit was never as jarring when I noticed it there.
